ABSTRACT:
A safety-adapted pivoted closure device for vessels containing volatile or flammable liquids is disclosed. The disclosed pivoted closure device has a flash arrester and safety vent, with the resulting device being positionable on a vessel, such as a portable receptacle containing gasoline. A spring biases a closure cap on the device toward a closed position, and the spring bias is overcome if a predetermined pressure build-up occurs within the vessel to thus allow the pressure to be relieved. Should this occur, gas and/or fumes are expelled from the vessel, but only through the flash arrester. A handle and linkage assembly are provided for manually moving the cap from a closed position to open the receptacle by overcoming the spring bias thereon with the handle and linkage assembly being designed so as not to prevent release of a pressure build-up within the vessel while the cap is in a closed position. The handle is operatively connected with a linking arm of the linkage assembly by means of a bail, and the handle is movable to a position near the vessel for storage purposes or to prevent accidental opening of the vessel. The device also includes a cylindrical member for adapting a conventional receptacle to receive the safety adapted, pivoted closure device.
